Fantasy world where they have been breeding dragons to be smaller and smaller until they have little toy dragons that can sit in your lap and are popular among noble ladies and if you leave them unattended in a home they will gather up all the low denomination change under dressers and such and push them into a corner to make a tiny $4.78 hoard to sit on
Imagine opening up your closet door and there in the back of your closet is your lap dragon, sitting on a rudimentary hoard of six nickels and 17 pennies. "Graaaak!", it says, as it spreads its wings wide (span 2ft 3in). The threat display is made somewhat less terrifying by its head getting caught in the underside of a coat, causing it to flap around briefly
